Renewable Energy In Germany
Renewable energy in Germany is mainly based on wind and biomass, plus solar and hydro. Germany had the world's largest photovoltaic installed capacity until 2014, and as of 2021 it has over 58 GW. It is also the world's third country by installed total wind power capacity, 64 GW in 2021 (59 GW in 2018https://windeurope.org/wp-content/uploads/files/about-wind/statistics/WindEurope-Annual-Statistics-2018.pdf ) and second for offshore wind, with over 7 GW. Germany has been called "the world's first major renewable energy economy". The share of renewable electricity rose from just 3.4% of gross electricity consumption in 1990, provided by conventional hydro, to exceed 10% by 2005 thanks to additional biomass and wind, and reaching 42.1% of consumption in 2019. As with most countries, the transition to renewable energy in the transport and heating and cooling sectors has been considerably slower. According to official figures, around 370,000 people were employed in the renewable e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogas
Biogas is a mixture of gases, primarily consisting of methane, carbon dioxide and hydrogen sulphide, produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste and food waste. It is a renewable energy source. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogen inside an anaerobic digester, biodigester or a bioreactor. Biogas is primarily methane () and carbon dioxide () and may have small amounts of hydrogen sulfide (), moisture and siloxanes. The gases methane, hydrogen, and carbon monoxide () can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. Biogas can be compressed after removal of carbon dioxide and hydrogen sulphide, the same way as natural gas is compressed to CN ...

Energy In Germany
Germany predominantly sources its energy from fossil fuels, followed by wind, nuclear power, solar, biomass (wood and biofuels) and hydro. The German economy is large and developed, ranking fourth in the world by nominal GDP. Germany is seventh in global primary energy consumption as of 2020. As of 2021, German primary energy consumption amounted to 12,193 Petajoule, with more than 75% coming from fossil sources, 6.2% from nuclear energy and 16.1% from renewables.https://www.bdew.de/media/documents/Jahresbericht_2021_korrigiert_19Jan2022.pdf In 2021 Germany's electricity production reached 553.9 TWh, down from 631.4 TWh in 2013. Key to Germany's energy policies and politics is the " Energiewende", meaning "energy turnaround" or "energy transformation". The policy includes phasing out nuclear power by 2022, and progressive replacement of fossil fuels by renewables. The nuclear electricity production lost in Germany's phase-out was primarily replaced with coal electricity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petajoule
The joule ( , ; symbol: J) is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889). Definition In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule can also be defined by any of the following: * The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V). This relationship can be used to define the volt. * The work required to produce one watt of power for one second, or one watt-second (W⋅s) (compare kilowatt-hour, which is 3.6 megajoules). This relationship can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primary Energy
Primary energy (PE) is an energy form found in nature that has not been subjected to any human engineered conversion process. It is energy contained in raw fuels, and other forms of energy, including waste, received as input to a system. Primary energy can be non-renewable or renewable. Where primary energy is used to describe fossil fuels, the embodied energy of the fuel is available as thermal energy and around 70% is typically lost in conversion to electrical or mechanical energy. There is a similar 60-80% conversion loss when solar and wind energy is converted to electricity, but today's UN conventions on energy statistics counts the electricity made from wind and solar as the primary energy itself for these sources. One consequence of this counting method is that the contribution of wind and solar energy is under reported compared to fossil energy sources, and there is hence an international debate on how to count primary energy from wind and solar. Primary energy is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Ministry For Economic Affairs And Energy
The Federal Ministry for Economic Affairs and Climate Action (german: Bundesministerium für Wirtschaft und Klimaschutz, ), abbreviated BMWK (was BMWi), is a cabinet-level ministry of the Federal Republic of Germany. It was previously known as the "Ministry of Economy". It was recreated in 2005 as "Ministry of Economics and Technology" after it had previously been merged with other ministries to form the Federal Ministry for Economics and Labour between 2002 and 2005. The ministry is advised by the Council of Advisors on Digital Economy. History The historical predecessor of the current Federal Ministry for Economic Affairs and Climate Action was the ''Reichswirtschaftsamt'' (Reich Economic Office), founded in 1917. In 1919, this became the ''Reichswirtschaftsministerium'' (Reich Ministry of Economy), which existed until 1945. In postwar occupied Germany, its functions were exercised by the Administrative Office of Economy (german: Verwaltungsamt für Wirtschaft) between 1946 ...

COVID-19 Pandemic In Germany
The COVID-19 pandemic in Germany has resulted in confirmed cases of COVID-19 and deaths. On 27 January 2020, the first case in Germany was confirmed near Munich, Bavaria. By mid February, the arising cluster of cases had been fully contained. On 25 and 26 February, multiple cases related to the Italian outbreak were detected in Baden-Württemberg. A carnival event on 15 February in Heinsberg, North Rhine-Westphalia, was attended by a man identified as positive on 25 February; in the outbreak which subsequently developed from infected participants, authorities were mostly no longer able to trace the likely chains of infections. On 9 March, the first two deaths in Germany were reported from Essen and Heinsberg. New clusters were introduced in other regions via Heinsberg as well as via people arriving from China, Iran and Italy, from where non-Germans could arrive by plane until 17–18 March. From 13 March, German states mandated school and kindergarten c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marginal Cost
In economics, the marginal cost is the change in the total cost that arises when the quantity produced is incremented, the cost of producing additional quantity. In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount. As Figure 1 shows, the marginal cost is measured in dollars per unit, whereas total cost is in dollars, and the marginal cost is the slope of the total cost, the rate at which it increases with output. Marginal cost is different from average cost, which is the total cost divided by the number of units produced. At each level of production and time period being considered, marginal cost includes all costs that vary with the level of production, whereas costs that do not vary with production are fixed. For example, the marginal cost of producing an automobile will include the costs of labor and parts needed for the additional automobile but not the ...

Renewable Electricity
Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

Directive On Electricity Production From Renewable Energy Sources
Directive 2001/77/EC is a European Union Directive for promoting renewable energy use in electricity generation. It is popularly known as the RES Directive. The directive, which took effect in October 2001, sets national indicative targets for renewable energy production from individual member states. As the name implies, the EU does not strictly enforce these targets. However, The European Commission monitors the progress of the member states of the European Union – and will, if necessary, propose mandatory targets for those who miss their goals. These objectives contribute toward achieving the overall indicative EU targets, which are listed in the white paper on renewable sources of energy. Regulators want a 12% share of gross renewable domestic energy consumption Domestic energy consumption is the total amount of energy used in a house for household work. The amount of energy used per household varies widely depending on the standard of living of the country, the climat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
